It is wild how cheap are solar panels now. Really, bonkers cheap. A huge rooftop solar panel costs less than 100 USD. From everything that I read/see/watch, most of the cost associated with solar panel arrays is the labour required for installation. (No hate on those folks -- they are skilled labour!)
